행사·컨퍼런스·세미나 포스터

Original prompt

[Input]
- language: Korean
- output_size: 1024x1536
- target_format: vertical event poster for print, mobile sharing, and venue signage

[Purpose]
Korean conference / seminar / lecture official poster, print-ready and SNS-shareable vertical layout.
Create a polished event promotion poster with a realistic conference identity system: strong title, practical registration information, speaker lineup, program highlights, sponsor area, and a clear CTA for online pre-registration.

[Composition]
- Main title area occupies the top 22% of the poster, with {행사명} as the primary focal point and {부제_태그라인} directly beneath it in smaller type.
- Add a small editorial event label near the header: {행사라벨}, set like a premium forum series marker or session code.
- Middle section uses a structured grid: left-side event facts panel for {일자}, {시간}, {장소}, {주소}; right-side speaker portrait cards or editorial avatar illustrations for {주요연사}.
- Center-lower section includes a program highlight band showing {프로그램}, with time blocks, small divider lines, and conference-session icons such as keynote, panel talk, workshop, and networking.
- Bottom section contains ticket and registration information: {티켓정보}, sponsor/host line {주최후원}, contact line {문의}, and a high-contrast CTA strip for {CTA}.
- Include realistic poster details: QR-style registration box, small ticket badge, venue floor label, sponsor footer, subtle geometric stage-light arcs, grid coordinates, and thin gold divider rules that reinforce the conference theme.
- Background treatment: deep navy, black, or charcoal surface with premium paper grain, faint architectural grid, soft spotlight gradients, and restrained metallic gold accents.

[3. CORE STRUCTURE]
- Header block (top 22%): Place {행사라벨} above the title in small caps or compact Korean/English mixed styling; place {행사명} in large bold sans-serif with strong visual weight and tight line spacing.
- Tagline line: Place {부제_태그라인} immediately below the title in smaller medium-weight type, using warm off-white or pale gold for hierarchy and readability.
- Event facts panel (mid-left 28–32%): Stack {일자}, {시간}, {장소}, and {주소} with icon-like labels such as DATE, TIME, VENUE, ADDRESS; use thin rules, small numerals, and structured spacing like a real conference poster.
- Speaker block (mid-right 28–32%): Display {주요연사} as 3–5 labeled speaker cards, paired with circular or rounded-rectangle portrait crops, monochrome silhouette portraits, or refined vector avatar illustrations. Add small role tags like KEYNOTE, CTO TALK, CREATOR SESSION.
- Program band (lower-middle 16–20%): Render {프로그램} as a compact schedule strip with time chips, session separators, and small decorative timeline dots.
- Ticket / registration area (bottom 14–16%): Place {티켓정보} next to a QR-style registration square; place {CTA} inside a solid highlight bar or bordered band sized for quick recognition on mobile.
- Sponsor footer: Place {주최후원} and {문의} in a formal footer area with small logo-like wordmarks, sponsor tiers, and publication-style microtext.
- Decorative graphics: Add thin gold rules, abstract conference stage lines, modular grid coordinates, subtle spotlight beams, and small directional arrows to create an official event-system feel.

[4. STYLE RULES]
- Typography: Pretendard or Noto Sans KR for Korean + Inter or Helvetica Neue for English, bold weights for {행사명}, medium weights for {부제_태그라인}, regular/semibold for details; title size should dominate the poster while supporting text stays compact and legible.
- Color palette: use {컨셉톤} as the governing palette, with specific tones such as navy #0B1F3A, black #111111, gold #C8A96A, warm off-white #F5F1E8, muted gray #A7B0BC, and a controlled accent blue #2F6BFF if needed for registration highlights.
- Layout language: premium corporate editorial design with modular panels, session labels, sponsor footer, and QR/ticket elements; all text blocks should feel intentionally typeset for a real conference.
- Border/shadow: thin gold separators, 1–2px rules, soft panel shadows, and subtle metallic linework may be used for depth; avoid turning the poster into a party flyer.
- Information hierarchy: {행사명} first, {일자}/{시간}/{장소} second, {CTA} third, with speaker and program details readable after a quick glance.

[5. VISUAL STYLE]
- Camera / lens: if using speaker photos, treat them like editorial portrait cutouts shot on an 85mm f/1.4 lens with shallow depth of field; if no photos, use clean vector-style profile placeholders with consistent framing.
- Lighting: studio softbox key light from upper-left at 45° with a faint fill from right; for portrait imagery, keep skin tones even and conference-portrait neutral.
- Color grade: deep navy + black base with restrained gold accents, crisp neutral whites, and slight cool contrast for a premium corporate-event look.
- Print finish impression: matte coated paper texture, crisp ink edges, subtle foil-like gold line accents, and high-resolution typography suitable for a 1024x1536 vertical poster.

[6. MOOD]
Institutional keynote poster — similar to a TEDx / conference identity system with a polished editorial layout, practical registration details, sponsor credibility, and premium corporate clarity.

- Layout invariants: event title must be the largest text; date, time, venue, ticket info, and CTA must remain clearly legible; speaker names must not overlap with other blocks.
- If profile photos are used, faces must be cleanly cropped and consistently sized; no distorted facial features.
- QR-style box, sponsor footer, and program strip should look like part of a real event poster, not random ornaments.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications that imply government or institutional approval
- Broken Korean characters or unreadable Hangul
- Celebrity composites or recognizable public figures used as speakers without explicit request
